GUARD FOR LOO-SE LEAF BINDERS Filed April 14, 1935 I 2 Sheets-Sheet 2 Patented Aug. 14, 1934 UNITED STATES PATE'r oer-" ce 1,970,516 GUARD FOR L O E LEAF RS Albert 1). Sutton, San Antonio, Tex. Application. April 14, 1933, Serial. No. 666,195 5' Claims. (01. mo -19 )v This invention relates to a new type ofguard for any size or type ofloosele'af binder and is especially. adapted to large record'b'ooks such as deeds, records and the like, in which the pages I 5. are of the looseleaf typeand are, or may be, inserted from time to tinieas'the book 'is' filled until the book is completed The guards may be fastened to the binder by means of apos't or posts or they may be sewed together and bound in book 10. form.

In some looseleafbindersas at present constructed the sheet is carrieddirectly by the posts. Because of this fact, when a large looseleai recrd book is completed a large portion ofthe space closest to the post iswasted on account orthe fact that the sheet or leaf cannot lie flat when the book is opened.

A main purpose of the present invention is the saving of this space which is now wasted because the leaves or sheets being carried directly bythe posts cannot lie flat when the book' is opened, while the leaves or sheets in'the looseleaf book using the guard of this invention will lie flat when the book is opened and'the entire sheetwill be usable and visible as well as readable regardless ofwhat place the book is opened. In other words the new guard accomplishes for a looseleaf binder what is now'accomplishedin a regularly bound book. 1 r

A main purpose of the invention is to provide an intermediate element which extends between the post and the leavesof the book. This intermediate element is carried by the posts and the leaves are hingedly secured to a hinged portion upon the intermediate element.

With these and other objects in view as will become apparent as the description proceeds, the invention consists in the combination of parts and elements set forth in detail below, claimed in the claims and shown in the drawings, in which Figure 1 is a side elevational view of a guard with leaves attached,

Referring tothe drawings in which like reier- Z5 ence characters indicate like parts throughout the various figures, 19 indicates the guard generally and is composed of two parts llarid 12'. The. part 11 comprises interior'layers 13 of cardboard or the like covered upon each side with clothpr fabric 14 which extends over and covers'the' interior layers 15 of cardboard or the like disDOSed within the part 12 of the guard. The cardboard layers 13 and 15 which may be jute tag or the like are spaced a short distance from one another 5 as shown particularly in Figures 3. and 4 so as to provide a hinge 16 extending from the t'opto the bottom of the guard composed entirely or the cloth or fabric 14. The layers 13,, I5 and the cloth fabric is are secured together by adhesive or fasteners of any type desired. The part 11 of the guard is provided with apertures 17 designed to receive the posts of the looseleaf binder.

' The above construction describes the'guard itself which is secured to the posts of the binder in the same manner as loose leaves are at present securedl In case the binder does not use posts, he he a t of thes a is odified a to be secured to whatever type of securing" means is used by the binder.

The construction whereby the leaves are secured to the part 12 will now be described. The cloth fabric 14 preferably extends around the inside edge 18 of the part 12 and the edge 18 is cut out at the portions 19 so as to leave the portions 20 5 which form hinges for the reception of a locking pin 21. The loose leaves 22 are also provided with cut-out portions 23 designed to accommodate the hinge portions 20 of the part 12.

The locking pin 21 passes through the hinge 1110 portion as shown particularly in Figure 2 of the drawings and has a flattened portion 24 located preferably at one of the hinge portions 20 and this flattened portion 24 is provided with an aperture 25 through which extends a locking brad 26, shown more particularly in Figure 3. The loose leaves 22 are of the double leaf size and the apertures 23 are placed at the central portion thereof. Each guard accommodates a plurality of leaves.

By means of the construction set forth above it is obvious that the book may be opened at any desired place and the leaves when opened will lie in substantially flat condition. v

In Figures 6 and 7 a modification of the locking pin 21 is shown according to which the locking pin has an enlarged portion 27 provided with an annular groove 28. The locking brad 26 in this case instead of passing through an aperture, fits into the groove 28. It may if desired be flattened into said groove by a blow after the locking pin has been properly positioned.

In Figures 8, 9, 10, 11 and 12 a further modification of the guard is shown making the same adaptable to the use of steel many other suitable metal. As above described with reference to the construction shown in Figure 1, the modified guard comprises two elements 30 and 31 which are composed of metal and, since they are composed of metal, they may be hinged together by means of hinges 32 through which passes a looking pin 33 which may be secured in position by means of the flattened portion 24, the aperture 25 and the locking brad 26, as previously described.

The part 30 is provided with apertures 17 as in the previous modification, or any means rendering the same capable of being secured to the binder. The steel guard may if desired for ornamental purposes, be covered with cloth or finished in any desired way.

Upon the inward edge of the part 31 hinges 34 are provided to which the leaves 22 are secured by the locking pin 35 of the same type as previously described. The pin 35 is provided with the fiattened portion 24, the aperture 25 and the locking brad 26, as previously described and shown more particularly in Figure 9.

In Figure 10 a modification of the locking pin particularly adapted for the metal construction is shown. In this modification the locking pin 35 is provided with a threaded portion 36 and one of the hinges 34 is threaded to accommodate the threaded portion 36 and after the threaded portion 36 has engaged the threaded portion of the hinge 34, the threads may be distorted by a blow from a hammer or other instrument so as to permanently lock the two together. It is obvious that various types of locking means may be employed in both constructions for securing the locking pin to the various types of hinges provided.

.Various advantages follow from the use of the above construction and these may be briefly set forth as follows. The entire sheet may be used,

the book can be easily opened, ease and comfort is provided by reading a page lying perfectly fiat, the ease with which a soiled page or sheet may be replaced is increased since it is merely necessary to remove such page from its respective guard and not release the entire binder and lastly, a greater protection is provided against tearing, It will be noted that an essential characteristic of the invention resides in the providing of a double hinge for each sheet of paper.

It is understood that the above embodiments are merely the preferred embodiments and are not to be construed in a limiting sense, but all embodiments such as will fall clearly within the scope of the appended claims are to be included within the scope of the invention.
